/**
 *  Quota configuration helps to achieve fairness and budgeting in service
 *  usage.
 *
 *  The metric based quota configuration works this way:
 *  - The service configuration defines a set of metrics.
 *  - For API calls, the quota.metric_rules maps methods to metrics with
 *    corresponding costs.
 *  - The quota.limits defines limits on the metrics, which will be used for
 *    quota checks at runtime.
 *
 *  An example quota configuration in yaml format:
 *
 *     quota:
 *       limits:
 *
 *       - name: apiWriteQpsPerProject
 *         metric: library.googleapis.com/write_calls
 *         unit: "1/min/{project}"  # rate limit for consumer projects
 *         values:
 *           STANDARD: 10000
 *
 *
 *       # The metric rules bind all methods to the read_calls metric,
 *       # except for the UpdateBook and DeleteBook methods. These two methods
 *       # are mapped to the write_calls metric, with the UpdateBook method
 *       # consuming at twice rate as the DeleteBook method.
 *       metric_rules:
 *       - selector: "*"
 *         metric_costs:
 *           library.googleapis.com/read_calls: 1
 *       - selector: google.example.library.v1.LibraryService.UpdateBook
 *         metric_costs:
 *           library.googleapis.com/write_calls: 2
 *       - selector: google.example.library.v1.LibraryService.DeleteBook
 *         metric_costs:
 *           library.googleapis.com/write_calls: 1
 *
 *   Corresponding Metric definition:
 *
 *       metrics:
 *       - name: library.googleapis.com/read_calls
 *         display_name: Read requests
 *         metric_kind: DELTA
 *         value_type: INT64
 *
 *       - name: library.googleapis.com/write_calls
 *         display_name: Write requests
 *         metric_kind: DELTA
 *         value_type: INT64
